JOHN H. YARBRAUGH, OF REDBIRD, ARKANSAS.

CHURN.

Specification of Letters Patent.

Patented June 6, 1916.

Application filed September 26, 1914. Serial No. 863,662.

To @ZZ v'whom it may concern:

Be it known that I, JOHN H. Yaesu-icon, a citizen of the United States, residing at Redbird, in the county of Montgomery and State or" Arkansas, have. invented new and useful lmprcvements in Churns, of which the following is a specification.

'I he invent-ion relates to churns and more particularly to the class of driving gear 19 mechanisms for churn dashers.

The primary object ot the invention is the provision ot mechanism ot this characte'r which can be fastened to the lid of a churn so that the dasher can be automatically operated for the rotation thereof, the said mechanism being of novel form to per# mit the release of the flasher on the removal of' the lidfrom the churn so that the dasher will remain in the body of the churn and 20 thus the same can be easily cleaned when taken from the churn.

Another object of the invention is the provision of mechanism of this character wherein the dasher can be vertically adjusted so that it may be raised or lowered within the body ot the churn as the occasion may require in carrying forth the churning4 process. l

A turther object ot the invention 1s the so provision of a `churn wherein the lid or cover can be readily clamped on the body `ot the. churn without necessitating adjustmentl ot the several clamping members. Thus the lid can be fastened in a quick and convenient manner on the churn or 'detached therefrom. the clamping members being adjustable so that the lid can be applied to the body ot the churn irrespective of the size thereof.

A. still further object of the invention is the provision of mechanism of this character wherein the clamping members are of novel form and are readily and easily adjustable and likewise the said mechanism can be readily attached to or detached from the lid, should the occasion require. A still further object of the invention is the provision ot mechanism ofy this charac ter which is extremely simple in construction, reliable and eiiicient in operation, and inexpensive in manufacture.

lilith these and other objects in view. the invention consists in the features of Construction. combination ot elements and arrangement or" parts as will be hereinafter fully described. illustrated in the accomtional view through the churn. Fig. 5 is' a similar view on the line 5v5 of Fig. 1. Fig. 6 is a vertical transverse sectional view through the gear mechanism. Fig. 7 is a. perspective view of thedasher.

Similar refe-rence characters indicate corresponding parts throughout the several views of the drawing.

Referring to the drawings in detail, 1()l designates the cylindrical body and 11 the A cover of the churn, the said body being made from any suitable material, while the cover is preferably made from wood, although it may be made from any other suitable material and is of circular shape corresponding the body and is adapted to rest upon the mouth edge of the latter which is formed with an external rim or bead 12. the cover 11 being detachably fastened to the body in a manner presently described.

`Arranged at three points on the cover or lid 11, at equidistances apart, are the clamping members 13,514 and 15 respectively, the two members 14 and. l5 being si'llarly const-ructed and aretforr'ned with jaws 16 which are adapted to grip the bead 1'2on the adjustment of the member 13 which is likewise formed with a jaw 17 corresponding to the jaws 16 and is adapted to grip the said bead 12. The two members 14 and 15 are formed with` elongated slots 18 in the Shanks thereof and through which are passed the bolt members 19, the same being also passed through the lid or cover 11 and carry the usual nuts 2O which work against the locking plates 21 surroundingthe bolt members 19 -and which are formed with teeth 22 which coperate with teeth Q3 formed on the Shanks of the members 14 and 15 so that on the tightening of the nuts 20, the

said clamping members will be fastened in l adjusted positions.

The clamping member 13 has its shank at one edge formed with rack teeth 24, the same meshing with the teeth 25 on a sector 26, rotatably supported upon a pivot 27. which is engaged inthe lid or cover 11 and a guide roo plate secured to the said lid or cover and in which is slidably fitted the shank of the clamping member 13, the sector 26 being formed with a lever 29 which permits the.

movement thereof for adjusting the said clamping member 13 so that the lid or cover can be firmly fastened to the body oit' the churn. edge 30 which traverses segmental-shaped toothed rack 31 fixed to the lid 0r cover 11 so that the lever can be held in. adjusted position on engagement of-the knife edge 30 with any one of the teeth on thel rack and thereby prevent the accidental freeing of the lid or cover on the -body of the churn.

Supported centrally on the lid or cover 11 is a. gear frame 3Q, which is in the form of a fork having Iiournaled in one limb 33 thereof. the stud axle 34,01? a driving gear while adjustably supported o n the other limb 3G of the frame, is a U-shaped bearing 3T in which is loosely itted the dasheil rod or stem 38 which is also passed through a central opening 39 in the base of the frame, the lower end of the stem or rod being fitted or formed with a fan-wheel-like dasher 40 which is adapted to work in the body 10 oli the churn.

Surrounding the rod or stem 38 is a pinion 41, which meshes with the gear 35 and is loose upon the said stem or rod 3S, yet is oapable of being made fast thereto tl'irough the medium of a I@et screw 42 threaded in the pinion 41 so that on the loosening of the pinion.l the dasher stem or rod 38 can be readily detached from the frame supporting the gearing. The pinion 41 is formed with a hub extension 43 which projects into seats 44 formed in the respective cross web 45 of the frame and the bearing 37 so that the said pinion 41 will be held in place in the limb on removal of the stem or rod 38 therefrom. The'bearing 37 has mounted therein a binding screw 4G which extends through an elongated slot 47 formed in -the limb 36 and carries a nut 4S so that the said bearing 37 can be adjusted on the limb 3G to permit the removalof the pinion 417 when desired, and also to hold the same in proper position for engagement on the stem or rod 38 and in working relation to the driving gear 35 supported by the frame.

Mounted on the axle 34 ot the driving gear 35 is a hand crank 49 so that the said. driving gear can be manually rotated. while fixed in the limb 3G of the frame, is a handle'() which enables the Operator to steady the churn during the churning process.

The lever 29 is formed with a. knife usenet The bas-e of the frame 32 is formed with an externally threaded boss 51 which extends through a central opening- 52 in the lid or @over 11 and on this boss is engaged a locking collar or nut 53 so that the frame can be detachably fastened to the lid or cover as will be clearly obvious.

The churn is operated in the usual Wellknown manner by 'rotating the driving gear 35 which imparts similar movement to the dasher 40, the latter being capable of vertical adjustment by loosening the set screw 42 in the pinion 41 so that the stem or rod 38 is-free for sliding movement therethrough and also through the frame On the tightening of the set screw, the dasher will be held fast in adjusted position. Now, should it be desired to remove the lid or cover from the body' of the churn., the set screw 42 is loosened and the clamping mem-- ber 13 is shifted on working the sector 26 to free the lid or cover 11 from the body 10 of the churn, and on the raising of the said lid or cover, the dasher 40 will remain in the body of the churn after the lid o1' cover 1 has-been detached so that the said dasher can be readily and easily cleaned when freed and on its removal from the churn. y

From the foregoing. it is thought that the construction and manner of operation ot the device will be clearly understooch and therefore a more extended explanation has been omitted.

lil'lhat is claimed is:

In combination av .receptacle formed with an annular bead., a lid resting upon saidl bead.y a substantially L--shaped locking member having its long arm slotted and formed with a lseries of teeth and a short arm having its free extremity bent to engage under said bead, a bolt mounted in said lid passing through said slot and'engagig the tooth .portion of said limb, a second substantially L-shaped Aflocking member having the free end of the short arm shaped to engage said bead and its'long arm formed with a series of teeth, a segmental rack bar mounted upon said lid and a combined tobt-hed sector and handle cooperating with the teeth of said last mentioned member and said segmental, rack bar.

- In testimony whereof I aiiix my signature in presence of two witnesses.
